In a saucepan over medium heat, melt the butter and add the roasted garlic along with the flour.
Cook for a couple minutes and add the cream, milk and cheese and continue whisking until the sauce thickens.
Once the sauce has thickened, take it off heat, and add the seasonings and give it a good mix.
Use the sauce for your favorite recipes, and top with some extra roasted cloves of garlic.
Notes
If you don’t have roasted garlic, you can also just quickly pan-roast some fresh garlic. To do this, you’ll need to use fresh garlic, specifically minced garlic.
To thicken the sauce, you can add some more half-and-half or heavy whipping cream into the mix.
To loosen up the sauce, add some more cream or milk and let it simmer for a minute or two.
The best way to store your leftover garlic sauce is to transfer it to an airtight container and refrigerate it for up to a week.
Remember that the consistency of the sauce will thicken up as it cools down, but it should loosen up as you warm it up. If you still want the sauce to be thinner, you can add a dash of milk into it while you’re reheating it.
I would recommend reheating the leftover sauce in the microwave, stirring it at every 20-second interval.
